How many times have you, after a particularly hard day, reached for some chocolate or ice cream? It’s common for many people, but for those trying to lose weight, it can be detrimental to their long term success, and most weight-loss programs never even address it.

They focus on choosing healthier foods and exercising more, but they never answer a key question: how can people who have eaten to cope with emotions change their eating habits, when they haven’t learned other ways of coping with emotions?

Researchers at Temple’s Center for Obesity Research are trying to figure out the answer as part of a new, NIH-funded weight loss study. The new treatment incorporates skills that directly address the emotional eating, and essentially adds those skills to a state-of-the art behavioral weight loss treatment.

“The problem that we’re trying to address is that the success rates for long-term weight loss are not as good as we would like them to be,” said Edie Goldbacher, a postdoctoral fellow at CORE. “Emotional eating may be one reason why people don’t do as well in behavioral weight loss groups, because these groups don’t address emotional eating or any of its contributing factors.”

The study has already had one wave of participants come through, and many participants have seen some success in the short term, but have also learned the skills to help them achieve long term success.

Janet Williams, part of that first cohort, said she lost about 17 pounds over 22 weeks, and still uses some of the techniques she learned in the study to help maintain her weight, which has not fluctuated.

“The program doesn’t just help you identify when you eat,” said Williams. “It helps you recognize triggers that make you eat, to help you break that cycle of reaching for food every time you feel bored, or frustrated, or sad.”

Williams said that the program teaches various techniques to help break that cycle, such as the “conveyor belt,” in which participants, when overcome with a specific emotion, can recognize it and take a step back, before reaching for chips or cookies, and put those feelings on their mental “conveyor belt” and watch them go away.

“I still use the skills I learned in the study,” she said. “I’ve learned to say, ‘I will not allow this emotional episode to control my eating habits.'”

People who are depressed appear to eat more chocolate than those who aren’t

Researchers at UC San Diego and UC Davis examined chocolate consumption and other dietary intake patterns among 931 men and women who were not using antidepressants. The participants were also given a depression screening test. Those who screened positive for possible depression consumed an average of 8.4 servings of chocolate — defined as one ounce of chocolate candy — per month. That compared with 5.4 servings per month among people who were not depressed.

Those who scored highest on the mood tests, indicating possible major depression, consumed an average of 11.8 servings per month. The findings were similar among women and men.

When the researchers controlled for other dietary factors that could be linked to mood — such as caffeine, fat and carbohydrate intake — they found only chocolate consumption correlated with mood.

It’s not clear how the two are linked, the authors wrote. It could be that depression stimulates chocolate cravings as a form of self-treatment. Chocolate prompts the release of certain chemicals in the brain, such as dopamine, that produce feelings of pleasure.

There is no evidence, however, that chocolate has a sustained benefit on improving mood. Like alcohol, chocolate may contribute a short-term boost in mood followed by a return to depression or a worsened mood. A study published in 2007 in the journal Appetite found that eating chocolate improved mood but only for about three minutes.

It’s also possible that depressed people seek chocolate to improve mood but that the trans fats in some chocolate counteract the effect of omega-3 fatty acid production in the body, the authors said in the paper. Omega-3 fatty acids are thought to improve mental health.

Another theory is that chocolate consumption contributes to depression or that some physiological mechanism, such as stress, drives both depression and chocolate cravings.

“It’s unlikely that chocolate makes people depressed,” said Marcia Levin Pelchat, a psychologist who studies food cravings at the Monell Chemical Senses Center in Philadelphia. She was not involved in the new study. “Most people believe the beneficial effects of chocolate are on mood and that they are learned. You eat chocolate; it makes you feel good, and sometime when you’re feeling badly it occurs to you, ‘Gee, if I eat some chocolate I might feel better.’ ”

Chocolate is popular in North America and Britain, she said. But in other cultures, different foods are considered pleasure-inducing pick-me-ups.

“In the United States, people consider chocolate really tasty,” Pelchat said. “It has a high cultural value. It’s an appropriate gift for Valentine’s Day. But in China, you might give stuffed snails to someone you really like.”
